@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data
A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE
COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM.
This is a list of recent vulnerabilities for which exploits are available. System administrators can use this list to help in prioritization of their remediation activities. The Qualys Vulnerability Research Team compiles this information based on various exploit frameworks, exploit databases, exploit kits and monitoring of internet activity.
ID: CVE-2015-0310
Title: Adobe Flash Player Memory Address Randomization Design Error
Security Bypass Vulnerability
Vendor: Adobe
Description: Adobe Flash Player before 13.0.0.262 and 14.x through 16.x
before 16.0.0.287 on Windows and OS X and before 11.2.202.438 on Linux
does not properly restrict discovery of memory addresses, which allows
attackers to bypass the ASLR protection mechanism on Windows, and have
an unspecified impact on other platforms, via unknown vectors, as
exploited in the wild in January 2015.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-10021
Title: WordPress WP Symposium 14.11 Shell Upload
Vendor: WP Symposium
Description: Unrestricted file upload vulnerability in UploadHandler.php
in the WP Symposium plugin 14.11 for WordPress allows remote attackers
to execute arbitrary code by uploading a file with an executable
extension, then accessing it via a direct request to the file in
server/php/.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)
ID: CVE-2014-9583
Title: ASUS WRT LAN Backdoor Command Execution
Vendor: ASUS
Description: common.c in infosvr in ASUS WRT firmware 3.0.0.4.376_1071,
3.0.0.376.2524-g0013f52, and other versions, as used in RT-AC66U,
RT-N66U, and other routers, does not properly check the MAC address for
a request, which allows remote attackers to bypass authentication and
execute arbitrary commands via a NET_CMD_ID_MANU_CMD packet to UDP port
9999. NOTE: this issue was incorrectly mapped to CVE-2014-10000, but
that ID is invalid due to its use as an example of the 2014 CVE ID
syntax change.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-4114
Title: Microsoft Windows OLE - Remote Code Execution "Sandworm" Exploit
(MS14-060)
Vendor: Microsoft
Description: Microsoft Windows Vista SP2, Windows Server 2008 SP2 and
R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold
and R2, and Windows RT Gold and 8.1 allow remote attackers to execute
arbitrary code via a crafted OLE object in an Office document, as
exploited in the wild with a "Sandworm" attack in June through October
2014, aka "Windows OLE Remote Code Execution Vulnerability."
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2014-7169
Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 bash43-025 processes trailing strings
after certain malformed function definitions in the values of
environment variables, which allows remote attackers to write to files
or possibly have unknown other impact via a crafted environment, as
demonstrated by vectors involving the ForceCommand feature in OpenSSH
sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server,
scripts executed by unspecified DHCP clients, and other situations in
which setting the environment occurs across a privilege boundary from
Bash execution. NOTE: this vulnerability exists because of an incomplete
fix for CVE-2014-6271.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-6271
Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 processes trailing strings after
function definitions in the values of environment variables, which
allows remote attackers to execute arbitrary code via a crafted
environment, as demonstrated by vectors involving the ForceCommand
feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache
HTTP Server, scripts executed by unspecified DHCP clients, and other
situations in which setting the environment occurs across a privilege
boundary from Bash execution, aka "ShellShock." NOTE: the original fix
for this issue was incorrect; CVE-2014-7169 has been assigned to cover
the vulnerability that is still present after the incorrect fix.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-0160
Title: OpenSSL TLS Heartbeat Extension Buffer Oveflow Information
Disclosure Vulnerability (Heartbleed)
Vendor: OpenSSL Project
Description: The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1
before 1.0.1g do not properly handle Heartbeart Extension packets, which
allows remote attackers to obtain sensitive information from process
memory via crafted packets that trigger a buffer over-read, as
demonstrated by reading private keys, related to d1_both.c and t1_lib.c.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:P/I:N/A:N)
